[0019] When describing embodiments of the present invention with reference to the drawings, Figure 1 shows a tidal power generation base constructed by a construction method in which a building aggregate made of a molding member of the inventor's patent is combined with concrete. A location suitable for tidal power generation 2 is determined parallel to land 1, and a self-propelled construction barge 5 equipped with a concrete plant 3 and a construction crane 4 is provided. On both lower side walls, a permanent storage tank A for floating garbage is provided, and in the center, a device for circulating seawater 6 to cool the generator 7 is connected. A tidal power generation equipment room B and a power generation room C equipped with a plurality of waterwheels 9 that generate electricity from tidal current 8 are provided to form a tidal power generation body D. The left and right walls on the offshore side of the tidal power generation body D are projected to form a tidal current receiving wall 10, and both side walls on the tidal current inlet side are connected to a dike 11 to ensure a large volume of tidal current 8.

[0025] As explained above, it is well known that electric vehicles are rapidly becoming more common. This invention recognizes that Japan, surrounded by a long coastline, has a wealth of regularly flowing tidal resources, and that electrifying fishing boats is an opportunity to help the declining fishing community. Therefore, this invention provides a method for constructing a tidal power generation base equipped with multiple hydroelectric generators that generate electricity using tidal currents, enabling the electrification of fishing boats.
[0026] Furthermore, since the boards and separators used in this invention are made from locally sourced timber from Japan, it can also contribute to revitalizing the struggling mountain village forestry industry in municipalities throughout Japan.

[0028] To illustrate an embodiment of the present invention with reference to the drawings, Figure 1 shows a tidal power generation base H constructed using the present inventor's patent, a construction method in which a series of structures made of molded members are joined together with concrete. The invention involves determining a suitable location for tidal power generation 2, constructing the seabed ground for the installation of the tidal power generation base H using a self-propelled construction barge 5, constructing the tidal power generation base structure G on the self-propelled construction barge 5, and pouring concrete 13 using sea sand collected from the seabed to create the tidal power generation base H, which is then installed at the designated location of the tidal power plant. The side walls of the tidal power generation base H are connected to a seawall 11 to provide a tidal current receiving wall 10, and a connecting passage is provided on top of the tidal current receiving wall 10 to connect the tidal power generation base H to the land 1. As a result, the tidal power generation base H becomes a source of income for the fisheries cooperative and can be used as an evacuation shelter F in the event of a disaster. Furthermore, it becomes possible to promote the use of electric fuel for fishing vessels and to provide free electricity for fishing vessels. On the other hand, the free electricity and fuel for fishing boats will revitalize fishing cooperatives, allowing them to concentrate on creating seaweed beds and artificial reefs, and also provide cooperation in dealing with the debris that washes ashore along the long coastline. [Example 2]
[0029] To explain the method of converting seawater into fresh water, the heat generated by the generator cooling water circulation system L, which cools the multiple generators 7 in the tidal power generation equipment room B, is used to convert seawater into fresh water, which is then stored in the fresh water storage tank at the tidal power generation base H. This fresh water is then supplied to urban areas through the water supply pipes 20 on land 1, enabling a response to the disruption of water infrastructure during disasters. On the other hand, Japan's water infrastructure is seriously aging and urgently needs to be renovated. In Japan, the role of the tidal power generation base H is significant, and the revenue from water sales is an important source of income for the declining fishing industry. [Example 3]
[0030] To explain the multi-purpose use of tidal power generation base H, the income generated by connecting both side walls on the tidal inlet side of tidal power generation base H to the seawall 11, utilizing the tidal pool as a fishing pond, and by using the outdoor restaurant at tidal power generation base H where fish from fish farm I can be eaten, will be an important source of income for the declining fishing industry. [Industrial applicability]
[0031] Our country, surrounded by a long coastline, has large fishing cooperatives where fishermen who protect this coastline gather, as well as shipyards that build boats. However, the drastic decline in fish catches is causing a loss of vitality. To revitalize this coastline, the present invention involves constructing tidal power generation bases equipped with multiple hydroelectric generators that generate electricity using tidal currents. By having fishing cooperatives and shipyards nationwide cooperate in installing these tidal power generation bases, which utilize the inexhaustible tidal energy that flows along the coastline day and night regardless of weather, it will be possible to promote the use of electric fuel in fishing boats and make electric fuel for fishing boats free. On the other hand, fishing cooperatives, revitalized by the free use of electric fuel for fishing boats, will be able to concentrate on seaweed bed creation and artificial reef construction. Furthermore, the cooperation of fishing cooperatives in the disposal of drifting debris that washes ashore along the long coastline can be obtained. [Brief explanation of the drawing]
